Benefits of technology

[0011]It is an object of the present invention to at least partially solve the problems in the conventional technology.

Problems solved by technology

The operation unit as described in First Document which realizes merely two types of control operations through operation by one finger has a problem that it cannot improve the operability of electronic devices to a satisfactory level.
Thus, a big challenge is to realize an operation unit which can improve the operability of electronic devices by allowing the electronic devices to execute still wider variety of control operations through the operation by one finger.
